Uji Aktivitas Antibakteri Ekstrak Etanol Daun Binahong (Anredera Cordifolia) Terhadap Bakteri Staphylococcus Aureus
Abstract
ABSTRACT Infectious diseases, especially skin infections caused by Staphylococcus aureus, are still a health problem, while the irrational use of antibiotics increases the risk of side effects and resistance, so safer antibacterial alternatives are needed such as binahong leaves (Anredera cordifolia) which are rich in secondary metabolites and have antibacterial potential. This study aims to determine the antibacterial activity of binahong leaf ethanol extract (Anredera cordifolia) against Staphylococcus aureus bacteria and to identify its active compound content. This study is a true experiment study with a posttest only control group design using a completely randomized design (CRD), consisting of 3 treatment groups of binahong leaf ethanol extract (Anredera cordifolia) at concentrations of 60%, 80%, and 100%, as well as positive and negative controls. The results of the antibacterial test showed that the ethanol extract of binahong leaves (Anredera cordifolia) had antibacterial activity against Staphylococcus aureus with an increase in the average diameter of the inhibition zone at a concentration of 60% (2.6 mm), 80% (6.2 mm), and 100% (11.6 mm), with a positive control of 22 mm and a negative control of 0 mm, and based on the results of GC-MS analysis identified six main compounds of binahong leaves (Anredera cordifolia) dominated by myo-inositol (64.28%). It can be concluded that the ethanol extract of binahong leaves (Anredera cordifolia) contains bioactive compounds and has antibacterial activity against Staphylococcus aureus bacteria.

ABSTRAK Penyakit infeksi, khususnya infeksi kulit akibat Staphylococcus aureus masih menjadi masalah kesehatan, sementara penggunaan antibiotik yang tidak rasional meningkatkan risiko efek samping dan resistensi, sehingga diperlukan alternatif antibakteri yang lebih aman seperti daun binahong (Anredera cordifolia) yang kaya metabolit sekunder dan berpotensi sebagai antibakteri. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri ekstrak etanol daun binahong (Anredera cordifolia) terhadap bakteri Staphylococcus aureus serta mengidentifikasi kandungan senyawa aktifnya. Penelitian ini merupakan penelitan true experiment dengan rancangan posttest only control groupmenggunakan rancangan acak lengkap (RAL), terdiri atas 3 kelompok perlakuan ekstrak etanol daun binahong (Anredera cordifolia) pada konsentrasi 60%, 80%, dan 100%, serta kontrol positif dan kontrol negatif. Hasil uji antibakteri menunjukkan bahwa ekstrak etanol daun binahong (Anredera cordifolia) memiliki aktivitas antibakteri terhadap Staphylococcus aureus dengan peningkatan rerata diameter zona hambat pada konsentrasi 60% (2,6 mm), 80% (6,2 mm), dan 100% (11,6 mm), dengan kontrol positif 22 mm dan kontrol negatif 0 mm, serta berdasarkan hasil analisis GC-MS teridentifikasi enam senyawa utama daun binahong (Anredera cordifolia) yang didominasi oleh myo-inositol (64,28%). Dapat disimpulkan bahwa ekstrak etanol daun binahong (Anredera cordifolia) mengandung senyawa bioaktif dan memiliki aktivitas antibakteri terhadap bakteri Staphylococcus aureus.
